Western New York's Tankless Water Heater Specialists
A tankless water heater is one of the smartest upgrades a Western NY homeowner can make — when it's installed right. The wrong size, the wrong vent, or an undersized gas line can leave you with a unit that struggles, throws error codes, or never delivers the hot water you were promised. We've been installing and repairing tankless systems for years. We'll size yours correctly, install it to code, and show you how to maintain it so you get the full 20+ year lifespan.

Frequently Asked Questions
Is a tankless water heater worth it?
For most Western NY homes, yes — especially if your current tank is nearing end of life. You'll never run out of hot water, your energy bills drop, and you free up basement space. The upfront cost is higher, but the unit lasts roughly twice as long.
Can my home support a tankless water heater?
Most can, but a few things need to be checked: gas line size, venting path, and electrical capacity. We do a full assessment before quoting so there are no surprises during the install.
How long does a tankless install take?
A straightforward replacement is usually a one-day job. New installs that require gas line upgrades or new venting can take a day and a half.
Do tankless water heaters need maintenance?
Yes — and this is where most homeowners go wrong. Western New York's hard water leaves scale inside the heat exchanger. An annual flush keeps the unit operating at full efficiency and protects your warranty.
What brands do you install?
We install all major tankless brands and will recommend the right model for your hot water demand and gas/electric setup.
Do you service tankless units installed by another company?
Yes. We'll diagnose error codes, descale, replace components, or repair venting issues regardless of who put it in.
